The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples.

In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, referring to fig. 1 to 2, a frame assembly 100 according to an embodiment of the first aspect of the present invention will be described.

As shown in fig. 1, a frame assembly 100 according to an embodiment of the present invention may include: the infrared device comprises a frame 1, a light guide structure 2 and an infrared device 3, wherein a first light channel 10a is arranged in the frame 1, the first light channel 10a extends along a first direction F1 (such as the inner and outer directions shown in FIG. 1), two ends of the first light channel 10a in the first direction F1 are respectively a first end and a second end, the first end (such as the inner end of the first light channel 10a shown in FIG. 1) is opened to form a light inlet and outlet 101, and the light inlet and outlet direction in the first light channel 10a is parallel to the first direction F1; the light guiding structure 2 is disposed at a second end inside the first light channel 10a (the outer end of the first light channel 10a shown in fig. 1); the infrared device 3 is disposed in the frame 1 and includes a substrate 31 and a lamp cap 32, the substrate 31 and the first light channel 10a are spaced apart from each other along a second direction F2 (a front-back direction as shown in fig. 1) perpendicular to the first direction F1, the lamp cap 32 is disposed on a side of the substrate 31 close to the first light channel 10a, wherein the light guide structure 2 is configured to change a light transmission direction, so that the lamp cap 32 transmits light through the light guide structure 2 and the light inlet/outlet 101.

Specifically, the frame 1 can protect the infrared device 3 and the light guide structure 2 disposed therein, and when the infrared device 3 is in operation, for example, when the lamp head 32 is an infrared emitting head, infrared light can be emitted outwards by the lamp head 32, and the infrared light can change direction through the light guide structure 2 to exit from the light inlet/outlet 101 to the outside of the frame 1; or, when the lamp head 32 is an infrared receiving head, the infrared light outside the frame 1 may enter the frame 1 from the light inlet/outlet 101, and then the direction of the infrared light is changed by the light guiding structure 2, so that the lamp head 32 can receive the infrared light. From this, through setting up light guide structure 2 for infrared light can be received and dispatched, thereby guarantees the normal realization of infrared touch function.

For example, in a specific example of the present invention, as shown in fig. 1, for the screen 200, a direction close to the center of the screen 200 is an inner side, i.e., an "inner" direction indicated by an arrow in the figure, and a direction away from the center of the screen 200 is an outer side, i.e., an "outer" direction indicated by an arrow in the figure, when the user uses the screen 200, a side of the screen 200 facing toward the user is a front side, i.e., a "front" direction indicated by an arrow in the figure, and conversely, a side of the screen 200 facing away from the user is a rear side, i.e., a "rear" direction indicated by an arrow in the figure.

As shown in fig. 1, a frame assembly 100 according to an embodiment of the present invention may include: the screen comprises a frame 1, a light guide structure 2 and an infrared device 3, wherein the frame 1 is suitable for being arranged at the edge of the screen 200, a first light channel 10a is arranged in the frame 1 and located at the front side of the screen 200, and one end (the inner end of the first light channel 10a shown in fig. 1) of the first light channel 10a close to the center of the screen 200 is opened as a light inlet and outlet 101. The light guide structure 2 is disposed in the first light channel 10a and located on a side of the light inlet/outlet 101 away from the center of the screen 200 (e.g., outside the light inlet/outlet 101 shown in fig. 1). The infrared device 3 is disposed in the frame 1 and located at the rear side of the first light channel 10a, the infrared device 3 may include a substrate 31 and a lamp cap 32 disposed at the front side of the substrate 31, and the lamp cap 32 transmits light with the light inlet and outlet 101 through the light guiding structure 2.

Moreover, through setting up light guide structure 2 for lamp holder 32 need not to set up towards inboard, the face light exit 101, and because lamp holder 32 locates the front side of base plate 31, lamp holder 32 sets up forward promptly, and infrared device 3 is located the rear side of first light passageway 10a, thereby can avoid lamp holder 32 to occupy the space in frame 1 front end, and then can realize the narrow limit design of frame 1 front end, improve the screen and account for the ratio. In addition, since the lamp head 32 is not disposed toward the rear side or the outside, the structure of the light guide structure 2 can be simplified, the transmission path of infrared light can be shortened, the attenuation of infrared light can be improved, and the reliability and effectiveness of the infrared touch function can be improved.

In some embodiments, as shown in fig. 1, the frame assembly 100 may further include: the blocking piece 4, light import and export 101 is located to the blocking piece 4 to can protect first light passageway 10a, light guide structure 2 and infrared device 3 by the blocking piece 4, avoid the foreign matter to enter into and damage light guide structure 2 and infrared device 3 in the first light passageway 10a, improve operational reliability. It will be appreciated that the closure 4 is of a material which is transparent to infrared light and also needs to be of a material which the closure 4 is not able to adversely affect the light at the light access 101.

For example, in some specific examples, the blocking member 4 may be a light filtering strip, so that the light passing through the light inlet and outlet 101 can be filtered by the blocking member 4, thereby improving the operational reliability of the infrared device 3.

In some embodiments, as shown in fig. 1, the blocking piece 4 extends obliquely in a direction from the first end to the second end of the first light passage 10a in a direction from the base 32 to the first light passage 10 a. For example, in some specific examples of the present invention, in any cross section of the frame 1, the length extension line of the light filter strip may be inclined toward the second end along a direction from the lamp head 32 to the first light channel 10a to intersect with the first direction F1 at an obtuse angle, for example, as shown in fig. 1, the length extension line of the light filter strip is inclined from back to front from inside to outside, so that the light filtering effect of the light filter strip can be improved.

In some embodiments, as shown in fig. 1, an included angle between the substrate 31 and the light entering/exiting line in the first light channel 10a is 0 ° ± 45 °, and an included angle between the light entering/exiting line of the lamp head 32 and the light entering/exiting line in the first light channel 10a is 90 ° ± 45 °, so that the design difficulty of the frame assembly 100 can be reduced, and the substrate 31 can be more conveniently mounted.

For example, in some embodiments, the included angle between the substrate 31 and the light entering and exiting from the first light channel 10a is 0 ° ± 45 °, for example, -45 °, -30 °, -15 °, 0 °, 15 °, 30 °, 45 °, and so on, it can be understood that, when the included angle between the substrate 31 and the light entering and exiting from the first light channel 10a is 0 °, the substrate 31 is parallel to the light entering and exiting from the first light channel 10a, so as to reduce the design difficulty of the frame assembly 100, and the substrate 31 can be more conveniently mounted.

For example, in some other embodiments, the included angle between the light entering and exiting from the light head 32 and the light entering and exiting from the first light path 10a is 90 ° ± 45 °, for example, 45 °, 60 °, 75 °, 90 °, 105 °, 120 °, 135 °, and so on, it can be understood that, when the included angle between the light entering and exiting from the light head 32 and the light entering and exiting from the first light path 10a is 90 °, the light entering and exiting from the light head 32 is perpendicular to the light entering and exiting from the first light path 10a, thereby reducing the design difficulty of the light guide structure 2.

In some embodiments, as shown in fig. 1, the frame 1 may include: the light guide structure comprises an inner frame 11, an outer frame 12 and a front frame 13, wherein the outer frame 12 and the inner frame 11 are distributed at intervals along a first direction F1, the outer frame 12 is arranged on one side (the outer side shown in fig. 1) of the inner frame 11 far away from the center of a screen 200, the front frame 13 is connected between the front end of the outer frame 12 and the front end of the inner frame 11, a light inlet and outlet 101 is formed on the inner frame 11 and is positioned at the connecting position of the inner frame 11 and the front frame 13 (namely, the light inlet and outlet 101 is defined between the inner end of the front frame 13 and the front end of the inner frame 11), and the light guide structure 2 is arranged at the connecting position of the outer frame 12 and the front frame 13 and comprises a reflecting surface 21 extending. Therefore, the frame 1 is simple in structure and convenient to process. At this time, the base 32 being disposed forward means that the base 32 is disposed on the side of the substrate 31 close to the front frame 13.

It should be noted that the material of the light guide structure 2 is not limited, and may be made of, for example, PC, PMMA, ABS and other plastic materials, and the manufacturing process of the reflective surface 21 of the light guide structure 2 is not limited, and for example, the reflective surface 21 may be polished to a high degree or sprayed with high-brightness UV paint, so that the reflective surface 21 is smooth like a mirror surface, and the condition of light reflection is satisfied, which is not described herein again.

In some embodiments, as shown in fig. 1, the reflecting surface 21 of the light guiding structure 2 is a plane and forms an angle a of 45 ° with the light entering and exiting from the first light channel 10a, so that the light can reflect the light emitted from the lamp head 32 along the second direction F2 to exit along a direction parallel to the first direction F1 under the action of the reflecting surface 21; or the incident light parallel to the first direction F1 can be reflected by the reflecting surface 21 and received by the base 2 along the second direction F2. In addition, the light guide structure 2 has a simple appearance, is convenient to machine and form, and is convenient to debug and install.

For example, in a specific embodiment according to the present invention, as shown in fig. 1, the reflecting surface 21 of the light guiding structure 2 is a plane and has an included angle a of 45 ° with the front frame 13, so that the light can reflect the emitted light of the lamp head 32 in the direction perpendicular to the front frame 13 to the direction parallel to the front frame 13 under the action of the reflecting surface 21; or the light beam incident in the direction parallel to the front frame 13 may be reflected by the reflecting surface 21 and then received by the base 2 in the vertical direction. In addition, the light guide structure 2 has a simple appearance, is convenient to machine and form, and is convenient to debug and install.

Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the substrate 31 may not be parallel to the front frame 13, and in this case, the reflecting surface 21 may be a curved surface or a plane with an included angle different from 45 ° with the front frame 13. That is, when the lamp head 32 is an emitting end and the direction of the emergent light is not perpendicular to the front frame 13, the reflecting surface 21 may be set to be a curved surface, so that the light reflected by the reflecting surface 21 may be changed into light in a direction parallel to the front frame 13; or when the reflecting surface 21 is a plane, the light reflected by the reflecting surface 21 can be changed into the light in the direction parallel to the front frame 13 by adjusting the included angle between the reflecting surface 21 and the front frame 13. On the contrary, when the lamp head 32 is a receiving end and the incident light is not perpendicular to the front frame 13, the reflecting surface 21 may be a curved surface, so that the light incident in a direction parallel to the front frame 13 may be received by the lamp head 32 after being reflected by the reflecting surface 21; or the reflecting surface 21 is set to be a plane, and the included angle between the reflecting surface 21 and the front frame 13 needs to be adjusted, so that the light entering in the direction parallel to the front frame 13 can be received by the lamp head 32 after being reflected by the reflecting surface 21.

For example, in an embodiment of the present invention, as shown in fig. 2, the base 32 is an emitting end, the base 31 is not parallel to the front frame 13, and the included angle between the base 31 and the front frame 13 is C (unit degree), when the reflecting surface 21 is a plane, according to the principle of light reflection, when a signal emitted from the base 32 can be transmitted in a direction parallel to the front frame 13 after being reflected by the reflecting surface 21, it should be satisfied that the included angle between the incident light and the normal of the reflecting surface 21 is equal to the included angle between the reflected light and the normal of the reflecting surface 21, and the normal of the reflecting surface 21 is a line perpendicular to the reflecting surface 21, and the included angle D (unit degree) between the reflecting surface 21 and the front frame 13 is calculated to be 45 degrees plus C/2 (unit degree), i.e. D ═ 45 ° + C/2, for example: assuming that the angle between the substrate 31 and the front bezel 13 is C equal to 20 °, the angle between the reflection surface 21 and the front bezel 13 is D equal to 55 °.

In some embodiments, as shown in fig. 1, the frame 1 is adapted to be disposed around the edge of the glass cover plate 2002, the inner frame 11 has a groove 111 recessed toward the outer frame 12, the groove 111 is located at the rear side of the light inlet/outlet 101, and the edge of the glass cover plate 2002 is adapted to be inserted into the groove 111 of the screen 200. Therefore, the frame 1 can be fixed on the screen 200, the connection reliability and the assembly efficiency of the frame 1 and the screen 200 are improved, and the frame 1 can protect the edge of the screen 200 to prolong the service life of the screen 200.

In some embodiments, as shown in fig. 1, the central plane of the groove 111 is parallel to the light entering and exiting from the first light channel 10a, so that the glass cover plate 2002 inserted into the groove 111 is also parallel to the light entering and exiting from the first light channel 10a, it is understood that the screen 200 is also parallel to the light entering and exiting from the first light channel 10 a. Therefore, the installation is more convenient, and the infrared touch function can be better realized.

In some embodiments, as shown in fig. 1, at least a portion of the lamp head 32 is located between the bottom wall 1111 of the groove 111 and the outer frame 12 to define a second light channel 10b, at least a portion of the lamp head 32 is located in the second light channel 10b, and the light incoming and outgoing direction of the lamp head 32 is the light incoming and outgoing direction of the second light channel 10b, so that the lamp head 32 can be ensured to smoothly receive or emit infrared light outwards, and the overall structural compactness of the frame assembly 100 can be improved.

For example, in an embodiment of the present invention, as shown in fig. 1, the light incoming and outgoing direction in the second light channel 10b is parallel to the second direction F2, the reflecting surface 21 is a plane and has an included angle a of 45 ° with the light incoming and outgoing direction in the first light channel 10a, and the reflecting surface 21 reflects the light transmitted along the first direction F1 as the light transmitted along the second direction F2 or reflects the light transmitted along the second direction F2 as the light transmitted along the first direction F1. Therefore, the lamp head 32 can be ensured to smoothly receive or emit infrared light, and the overall structure compactness of the frame assembly 100 can be improved.

In some embodiments, as shown in fig. 1, a distance a between at least a portion of the base 32 (i.e., a portion of the base 32 between the bottom wall 1111 of the groove 111 and the bezel 12) and the bottom wall 1111 of the groove 111 is equal to or greater than 0.5mm, and a distance B between at least a portion of the base 32 (i.e., a portion of the base 32 between the bottom wall 1111 of the groove 111 and the bezel 12) and the bezel 12 is equal to or greater than 0.5 mm. That is to say, the distance a between the lamp cap 32 and the bottom wall 1111 of the groove 111 and the distance B between the outer frame 12 are both greater than or equal to 0.5mm, so that the lamp cap 32 can be ensured to have a sufficient safety distance, the operational reliability of the infrared device 3 can be improved, and the narrow frame effect can be ensured.

In some embodiments, as shown in fig. 1, the outer frame 12 and the front frame 13 have a first positioning structure 15 thereon, and the light guiding structure 2 is positioned and fitted to the first positioning structure 15. This makes it possible to secure the light guide structure 2 and increase the structural stability of the entire housing assembly 100. Specifically, the first positioning structure 15 is not limited in structural form, for example, first protrusions 151 may be respectively provided at the intersection position of the outer frame 12 and the front frame 13, on the inner side wall of the outer frame 12 and on the rear side wall of the front frame 13 to constitute the first positioning structure 15, and the inner end and the rear end of the light guiding structure 2 are respectively clamped between the first protrusions 151 at the inner side and the rear side, thereby facilitating the processing and assembling.

In some embodiments, as shown in fig. 1, the outer frame 12 and the inner frame 11 each have a second positioning structure 16 thereon, and the substrate 31 is positioned and fitted to the second positioning structure 16. This makes it possible to firmly attach the substrate 31 and increase the structural stability of the entire housing assembly 100. Specifically, the structural form of the second positioning structure 16 is not limited, for example, two second protrusions 161 arranged at intervals may be arranged on the inner side wall of the outer frame 12, and a first groove 162 is formed in the middle of the two second protrusions 161; meanwhile, two second protrusions 161 are arranged on the outer side wall of the inner frame 11 at intervals, a first groove 162 is formed between the two second protrusions 161, and the inner end and the outer end of the substrate 31 are respectively clamped in the first grooves 162 on the inner side and the outer side, so that the processing and the assembly are convenient.

In some embodiments, as shown in fig. 1, the inner frame 11 and the front frame 13 have a third positioning structure 17 thereon, and the frame assembly 100 further includes a blocking member 4 (e.g., a light filter strip) disposed at the light inlet/outlet 101 and positioned and engaged with the third positioning structure 17. This makes it possible to firmly attach the closing material 4 and to increase the structural stability of the entire housing assembly 100. Specifically, the third positioning structure 17 is not limited in structure, for example, one third protrusion 171 may be provided at the front end of the inner frame 11 to be inserted into the positioning groove at the rear end of the blocking piece 4, while two third protrusions 171 are provided at the inner end of the front frame 13 at intervals, a third groove 172 is formed in the middle of the two third protrusions 171, and the front end of the blocking piece 4 has a protrusion inserted into the third groove 172, thereby facilitating the processing and assembling.
